Things. According to the fertilizer clogging detection mechanism 106,
Accurate detection can be performed with little influence from muddy water and muddy water in paddy fields. 107 is an adjusting device for the detection mechanism 106, which adjusts the detection sensitivity according to the field. That is, by adjusting the electric conduction resistance, when the muddy water in the field at the time when the fertilizer has not been scattered yet has sufficient electric conductivity, the detection mechanism operates to prevent false alarm.

 Next, the operation of the above example will be described.

First, when a large number of spare seedlings are to be mounted on the riding type traveling vehicle body 1 side, as shown in FIG. 1 and FIG.
31 is mounted on the front and rear brackets 29a and 29b to mount a large amount of seedlings. When it is not necessary to load a large amount of seedlings, the spare seedling placement devices 31 on both front sides or both rear sides may be removed.

In this state, when the seedlings are mounted on the seedling table 16 of the rice transplanting machine 14 and the granular fertilizer is stored in each fertilizer tank 41, and each transmission rotating unit is driven while the riding type traveling body 1 is moving forward, The seedling mounting table 16 reciprocates left and right, and the seedlings are fed to the lower end side. Then, the transplanting tool 18 swings with the rotation of the rotating case 17, and the transplanting claws move up and down in a closed loop-shaped transplantation locus, thereby dividing and holding one seedling per one plant from the seedling mounting table 16. Seedlings are planted on the soil surface of paddy fields that have been leveled with the leveling floats 20 and 21.

On the other hand, each drive shaft 53 of the fertilizer applicator 39 is rotationally transmitted in a certain direction via a drive rod 96, a lever 95, and a ratchet mechanism 94 by a crank 97 transmitted from a rotation shaft 98 of the rotation case 17 via gears 99 and 101. Is done. For this reason, when the clutch 54 is set to `` on '', the feeding roll 46 is rotated and the fertilizer is fed from the fertilizer tank 41 and discharged to the lower funnel 74,
It flows down in the transfer pipe 43 and is discharged to the opening of the groove generator 44.
At this time, the pressurized air from the blower 47a is stored in the air tank 47b, and this high-pressure air is blown into the transfer pipe 43 below the funnel 74 via the air conduit 48, thereby forcing fertilizer to flow down the transfer pipe 43. In this way, the fertilizer scattered in the groove opened by the groove generator 44 is transferred back into the groove device 44, and then the groove is buried back by the covering soil plate 108 and buried under the soil surface. .

In this way, the seedling planting operation and the fertilizing operation are performed simultaneously, but to adjust the amount of each fertilizer feeding device 42 respectively, the gear 90 is moved to disengage the gear 51,
The gear 51 is rotated forward or backward to move the gear 51 left and right with the screw of the cylinder shaft 50, thereby adjusting the feeding adjustment roll 46b.
It is good to move and adjust. In addition, in order to adjust the amount of each fertilizer feeding device 42 at once, the rotation shaft 89 can be rotated forward and reverse by the lever 88, so that the gear 51 is rotated by the gear 90, and the adjustment can be performed in the same manner as described above.

Next, when the work is completed and the fertilizer in the fertilizer tank 41 is discharged, the fertilizer take-out gutter 61 is opened as shown by the imaginary line in FIG. 8, and the moving member 66 equipped with the blocking brush 64 is moved. When the fertilizer is pulled out, the fertilizer in the tank 41 is received by the fertilizer takeoff gutter 61 and discharged as it is to the outside on the rear side. The discharged fertilizer may be appropriately received in a container.

In addition, when cleaning the feed roll 46 and other appropriate portions of the fertilizer feed device 42 and draining water after cleaning, the blower 47a is removed and the wind is blown to easily perform cleaning and draining.

In particular, a fertilizing frame 40 having a frame structure long in the lateral direction of the machine body is provided behind the sub-transmission case 15b of the rice transplanting machine 14.
The lower part is fixed, and a fertilizer tank 41 and a fertilizer feeding device 42 for feeding fertilizer from the fertilizer tank 41 are attached to the fertilizer application frame 40 in the lateral direction of the machine body.
15b Above the rear upper part, the fertilizer tank 41 of the fertilizer applicator 39 and the fertilizer feeding device 42 for feeding fertilizer from the fertilizer tank 41 can be compactly arranged by extending in the left-right direction of the machine body.
42 is a planting device 19 attached to the rear of the auxiliary transmission case 15b.
Therefore, the fertilizer fed from the fertilizer feeding device 42 is appropriately applied near the planting position immediately below, and the occurrence of clogging of the fertilizer is reduced and the fertilizer application can be performed appropriately.

Further, the lower part of the fertilizer application frame 40 having a frame structure long in the lateral direction of the machine body is fixed to the rear part of the sub-transmission case 15b of the rice transplanting machine 14, and the respective rotation shafts 98 provided at the rear end of each sub-transmission case 15b are fixed. The upper part of each drive rod 96 that moves up and down by being driven by the driving force is connected to the fertilizer feeding device 42 that feeds fertilizer to a seedling planted by the planting device 19 driven by each rotation shaft 98. Therefore, there is no need to provide a special drive system for driving each fertilizer feeding device 42 from the riding type traveling vehicle body 1 side, and it is possible to simply use the power for driving the planting device 19 by each sub-transmission case 15b, Of course, both are arranged at a relatively close position, and a load for driving each fertilizer feeding device 42 is applied to each rotating shaft 98, so that stable driving can be performed, so that the structure is simple and appropriate.
